Low LET radiation is typically associated with which type?

• A. Beta
• B. Gamma/ X-Rays
• C. Alpha
• D. Neutron

Answer: (B)

Low linear energy transfer means energy is deposited sparsely along the radiation’s path, creating ionizations at relatively low density. Gamma rays and X-rays are photons that interact mainly through secondary electrons, which travel some distance and spread out ionizations rather than piling them up in a dense cluster. This sparse energy deposition is the hallmark of low LET. In contrast, alpha particles are heavy charged particles that produce a dense burst of ionizations over a short range (high LET), and neutron interactions can also lead to dense ionization patterns. So the type typically associated with low LET is gamma rays and X-rays.
